I've had several users complain to me that while in the ECO creation screen, the file editing window for creating markups is way too small. i can see thier concern, I have a 22" monitor and even with that and my computer glasses I have a hard time doing markups in that tiny window. You can zoom in and out, but sometimes you need to be zoomed to the extents of the drawin or model to see what's what. You have the options to use the dwf viewer or Design Review... but then you cannot automatically create a markup linked to the ECO. The route it takes to create a markup in Design Review, and the manually Vault it and attach to the change order is convoluted at best. SOme of my users are not terribly CAD savvy or even computer savvy... so the easier the better. Some sort of larger markup window, maybe with more tools... would make everyone a happy camper.
